TYPO3 Core

Since version 10.4.29 the form editor display undefined for the element types.

The change from [SECURITY] Ensure text preview of multivalue items in form editor introduced these behaviour.

The information about the type is not available within the form element definition.

These affect only TYPO3 10. In TYPO3 11 the @label is used here. https://github.com/TYPO3/typo3/commit/c36447f2f4d719564993cfabe18f7fbeb565b9b3
